Convergence lost horizontal convergence only. Can not move the cross in the horizontal position on any color. TV worked fine, after 20 mins, the convergence went off center. Turned TV OFF, let cool, five mins later, still off.

My red has moved to the right. you cannot use the control to move it back, although you can move (red) up and down slightly. My other colours are fine I can adjust them and currently are fine. The picture looks like writing and images have a red double beside it. Seems like the gun is out of align.My red has moved to the right. you cannot use the control to move it back, although you can move (red) up and down slightly.

With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)

Reheat all the surface mount solder points on the Small Signal Board. Then realign the set including convergence menu. To enter service mode: power off the set for 10 sec, then hold down Vol- and Ch- buttons for 10 sec. See this link: Alignment Procedure (pdf)

Also download the Alignment procedure pdf file. Hope this will help you. Please let me know if the information was of any help to you or you need further assistance.

No colors alignment to any colors R,G,B.The tv convergence board are dead.The 2 STK convergence ICS and some or all it resistors must be to replaced to solved convergence problems.The shop will cost U $300-350 for parts and labors.

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

Symptom:Unit appears to have poor convergence due to:1. cross hatch appears tilted2. one color (or more) being larger than the others.

Cause:The yoke or yokes may have:(1) rotated slightly or (2) slipped down during transport.

Resolution:Loosen a yoke and lower to inspect the tape. If black tape is present remove it from under all yokes (white tape or no tape is OK). Slide yoke or yokes up tight against the CRT and tighten to prevent slipping or rotation. Precede with alignments and or convergence as necessary.

it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down

Your TV most likely has a problem in the convergence circuits. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

Screen looks 3D

Colors don't line up

One or more colors can't be adjusted when using the convergence menu.

Screen is bowed or warped.

Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

the left and right volume buttons are what move the convergence horizontally, so if they dont move you will need to replace the convergence ICs .if you need more info I will need the model number of your JVC

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3DOne or more colors can't be adjusted when using the convergence menu. Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
